Nope that's already unchecked for me... This is only happening in InDesign when I move objects, so i tried unplugging my second monitor and it stopped, as soon as I plugged it back in it started again... Is this something I can fix in a display setting?

I also noticed my tools are not working properly when I move them over to my second monitor...

I too am having this problem just purchased a Retina iMac last week when in indesign with a second monitor any movement in indesign causes my screen to go black. As above the problem does not happen when I disconnect the second monitor. Come on Adobe can you sort a fix out for this it is driving me crazy!

As reported in post #4, it may be a bug related to a second monitor. It would be helpful if those who posted can provide more information about their system configuration to confirm that it may be a new bug.

I've tried both InDesign CC 2014 & CC 2015, when I move objects with a mouse in InDesign the iMac monitor flashes black every 2nd or 3rd time when I release the mouse button. Tonight I unplugged the monitor and am working in CC 2014 and it is much better though still flashes every now and then, probably every few minutes again after moving an object.

For those still watching this thread I have come across one solution (though not very glamorous – not my solution by the way). If you go to "System Preferences – Accessibility – Displays" and increase the cursor size it seems to stop the flashing (for the moment). The thread I found, which I can't find now, said to take it to the second bar on cursor size, I found mine works at just over half way to the second bar which means the cursor isn't HUGE.

I also have this problem with an external 4k monitor and 2015 mbp. For this to still be an issue after all the $$$ paid for this subscription is VERY disappointing. In my case the issue presented itself when I switched to a 4k external. This should be a high priority fix for Adobe. Will file the bug report as suggested

I've been having a similar issue from BEFORE updating to "El Capitan." We hoped that updating to El Capitan would solve the problem. It hasn't. My issue started 2-3 weeks ago. Suddenly (not consistently) when using text tool, I click in a text box and the whole InDesign screen goes dark. When you release the click, it goes back to normal. Click in the box again -- black screen again. It's like a strobe light. The only way I get it to stop is to restart InDesign. I have one monitor only and I'm on a "Mid 2010 iMac." Anyone else having this issue??? When I research, I see people posting about Photoshop doing something similar, but have found nothing about InDesign doing it. I have filed a bug report already as well.

The entire screen flashes quickly to black and then returns to normal when I move files around. It does not happen all the time. As a matter of fact, most of the time it does not happen. It seems to happen more when I overlap files but I haven't been able to reliably repeat the problem in any specific pattern. This is only a problem in InDesign.

Many thanks for posting this temporary workaround. You may have saved my sanity! And to marthab88087726 – the "using the InDesign screen on the second monitor" also seemed to work. Neither are ideal, but work until the bug is fixed.

Side note FYI: I was also having flickering problems in Illustrator (placing images) and Photoshop (using brushes). Using these applications on the second monitor works, but the increased pointer size doesn't seem to fix the Photoshop issue.

It sounds like my problem is similar but different than everyone else's(?). My coworker and I only get the flashing black screen when using the text tool cursor inside a text box -- and it's very sporadic. For us, it isn't happening when moving objects and neither of us is using two monitors. However, I DID try something I saw posted about changing cursor size (in System Prefs under "accessibility") to one step above normal, and I have NOT had any issues since (and it's been a week now). Granted, I can't stand the larger cursor and it causes oddities in Photoshop with brushes, but the black flashing screen has not reappeared. I wonder if that would temporarily fix everyone else's issues with their flashing back screens?
